Polymeric compositions for sustained release of volatile materials

摘要

A polymeric composition comprising a copolymer obtained from at least one monomer comprising an ether group and at least one monomer not comprising an ether group, a compatible plasticizer and a volatile material is able to provide sustained delivery of the volatile material over a long period of time. Additionally, if the volatile material is a composition formed by several components of different volatility, the compositions of the present invention is able to provide a uniform release of all components of the volatile material.
